2 fix small memory leaks on compile-time failures
5 finish byte <-> utf8 and localencoding <-> utf8 conversions
6 make substr($bytestr,0,0,$charstr) do the right conversion
7 add Unicode::Map equivivalent to core
8 add support for I/O disciplines
9 - a way to specify disciplines when opening things:
10 open(F, "<:crlf :utf16", $file)
11 - a way to specify disciplines for an already opened handle:
12 binmode(STDIN, ":slurp :raw")
13 - a way to set default disciplines for all handle constructors:
14 use open IN => ":any", OUT => ":utf8", SYS => ":utf16"
15 eliminate need for "use utf8;"
16 autoload byte.pm when byte:: is seen by the parser
17 check uv_to_utf8() calls for buffer overflow
18 (see also "Locales", "Regexen", and "Miscellaneous")
21 support "use Thread;" under useithreads
23 - create new interpreter in a different thread
24 - exchange data between interpreters/threads
25 - share namespaces between interpreters/threads
26 work out consistent semantics for exit/die in threads
27 support for externally created threads?
31 auto-produce executable
32 typed lexicals should affect B::CC::load_pad
33 workarounds to help Win32
34 END blocks need saving in compiled output
36 fix comppadlist (names in comppad_name can have fake SvCUR
37 from where newASSIGNOP steals the field)
40 CPP-space: restrict what we export from headers when !PERL_CORE
41 header-space: move into CORE/perl/?
42 API-space: complete the list of things that constitute public api
45 fix the vicious cyclic multidependency of cc <-> libpth <-> loclibpth
46 libswanted <-> usethreads <-> use64bitint <-> use64bitall <->
48 make configuring+building away from source directory work (VPATH et al)
49 this is related to: cross-compilation configuring (see Todo)
50 _r support (see Todo for mode detailed description)
51 POSIX 1003.1 1996 Edition support--realtime stuff:
52 POSIX semaphores, message queues, shared memory, realtime clocks,
53 timers, signals (the metaconfig units mostly already exist for these)
54 UNIX98 support: reader-writer locks, realtime/asynchronous IO
55 IPv6 support: see RFC2292, RFC2553
58 figure out where the PV->NV->PV conversion gets it wrong at least
59 in AIX and Tru64 (V5.0 and onwards) when using long doubles: see the
60 regexp tricks we had to insert to t/comp/use.t and t/lib/bigfltpm.t,
61 (?:9|8999\d+) and the like.
64 Configure probe for quad_t, uquad_t, and (argh) u_quad_t, they might
65 be in some systems the only thing working as quadtype and uquadtype.
68 deprecate traditional/legacy locales?
69 How do locales work across packages?
70 figure out how to support Unicode locales
71 suggestion: integrate the IBM Classes for Unicode (ICU)
72 http://oss.software.ibm.com/developerworks/opensource/icu/project/
73 and check out also the Locale Converter:
74 http://alphaworks.ibm.com/tech/localeconverter
75 ICU is "portable, open-source Unicode library with:
76 charset-independent locales (with multiple locales simultaneously
77 supported in same thread; character conversions; formatting/parsing
78 for numbers, currencies, date/time and messages; message catalogs
79 (resources) ; transliteration, collation, normalization, and text
80 boundaries (grapheme, word, line-break))".
81 There is also 'iconv', either from XPG4 or GNU (glibc).
82 iconv is about character set conversions.
83 Either ICU or iconv would be valuable to get integrated
84 into Perl, Configure already probes for libiconv and <iconv.h>.
87 make RE engine thread-safe
88 a way to do full character set arithmetics: now one can do
89 addition, negate a whole class, and negate certain subclasses
90 (e.g. \D, [:^digit:]), but a more generic way to add/subtract/
91 intersect characters/classes, like described in the Unicode technical
92 report on Regular Expression Guidelines,
93 http://www.unicode.org/unicode/reports/tr18/
94 (amusingly, the TR notes that difference and intersection
95 can be done using "Perl-style look-ahead")
96 difference syntax? maybe [[:alpha:][^abc]] meaning
97 "all alphabetic expect a, b, and c"? or [[:alpha:]-[abc]]?
98 (maybe bad, as we explicitly disallow such 'ranges')
99 intersection syntax? maybe [[..]&[...]]?
100 POSIX [=bar=] and [.zap.] would nice too but there's no API for them
101 =bar= could be done with Unicode, though, see the Unicode TR #15 about
103 http://www.unicode.org/unicode/reports/tr15/
104 this is also a part of the Unicode 3.0:
105 http://www.unicode.org/unicode/uni2book/u2.html
106 executive summary: there are several different levels of 'equivalence'
110 use fchown, fchmod (and futimes?) internally when possible
111 use fchdir(how portable?)
112 create secure reliable portable temporary file modules
113 audit the standard utilities for security problems and fix them
117 alternate runops() for signal despatch
118 figure out how to die() in delayed sighandler
119 make Thread::Signal work under useithreads
122 sort out the spawnvp() mess for system('a','b','c') compatibility
123 work out DLL versioning
126 add new modules (Archive::Tar, Compress::Zlib, CPAN::FTP?)
127 sub-second sleep()? alarm()? time()? (integrate Time::HiRes?
128 Configure doesn't yet probe for usleep/nanosleep/ualarm but
130 floating point handling: nans, infinities, fp exception masks, etc.
131 at least the following interfaces exist: fp_classify(), fp_class(),
132 class(), isnan(), isinf(), isfinite(), finite(), isnormal(),
133 ordered(), fp_setmask(), fp_getmask(), fp_setround(), fp_getround(),
134 ieeefp.h, fp_class.h. There are metaconfig units for most of these.
135 Search for ifdef __osf__ in pp.c to find a temporary fix that
136 needs to be done right.
137 fix the basic arithmetics (+ - * / %) to preserve IVness/UVness if
138 both arguments are IVs/UVs
139 replace pod2html with new PodtoHtml? (requires other modules from CPAN)
140 automate testing with large parts of CPAN
141 Unicode collation? http://www.unicode.org/unicode/reports/tr10/
142 turn Cwd into an XS module? (Configure already probes for getcwd())
143 mmap for speeding up input? (Configure already probes for the mmap family)
144 sendmsg, recvmsg? (Configure doesn't probe for these but the units exist)
145 setitimer, getitimer? (the metaconfig units exist)
148 keep filenames 8.3 friendly, where feasible
149 upgrade to newer versions of all independently maintained modules
150 comprehensive perldelta.pod
153 describe new age patterns
154 update perl{guts,call,embed,xs} with additions, changes to API
155 convert more examples to use autovivified filehandles
156 document Win32 choices
157 spot-check all new modules for completeness
158 better docs for pack()/unpack()
159 reorg tutorials vs. reference sections
